Childhood-onset nephrotic syndrome is a kidney disorder characterized by severe proteinuria (excess proteins in the urine), hypoalbuminemia (low albumin levels in the blood), and edema (swelling) that affects approximately 2-7 per 100,000 children under 18 years of age annually.
Primary causes of nephrotic syndrome are usually described by their histology: [21] Minimal change disease (MCD): is the most common cause of nephrotic syndrome in children. It owes its name to the fact that the nephrons appear normal when viewed with an optical microscope as the lesions are only visible using an electron microscope .
Primary forms of glomerulonephrosis can occur at any age, although it is found in adults more commonly than children. The most common cause of glomerulonephrosis in children is Minimal Change Disease where they make up a majority of cases. There are 10-50 cases per 100,000 children, with male cases being twice as common as female cases. [16]
FSGS accounts for 35% of all cases of nephrotic syndrome, making it one of the most common causes of nephrotic syndrome in the United States. [8] FSGS accounts for 2% of all cases of kidney failure. [4] African American patients have four times the likelihood of developing FSGS. Men are about two times as likely to develop FSGS compared to ...
Minimal change disease (MCD), also known as lipoid nephrosis or nil disease, among others, is a disease affecting the kidneys which causes nephrotic syndrome. [1] Nephrotic syndrome leads to the loss of significant amounts of protein to the urine (proteinuria), which causes the widespread edema (soft tissue swelling) and impaired kidney function commonly experienced by those affected by the ...
[1] [3] NPHS1 mutations are the most common cause of primary congenital nephrotic syndrome, accounting for 40-80% of cases. [1] NPHS2: This gene encodes for the protein podocin. [1] Patients with this genetic mutation develop nephrotic syndrome in the first few weeks of infancy, but can also manifest symptoms later in life. [3]
Minimal change disease is characterised as a cause of nephrotic syndrome without visible changes in the glomerulus on microscopy. Minimal change disease typically presents with edema , an increase in proteins passed from urine and decrease in blood protein levels, and an increase in circulating lipids (i.e., nephrotic syndrome ) and is the most ...
By contrast, nephrotic syndrome is characterized by proteinuria and a constellation of other symptoms that specifically do not include hematuria. [6] Nephritic syndrome, like nephrotic syndrome, may involve low level of albumin in the blood due to the protein albumin moving from the blood to the urine. [7]
